The first person to watch something fall.

The first person to live.

Robert Hooke was the first person to observe cells.
He did not. The concept of gravity existed before Newton; everyone who has ever lived has known that things fall. Newton was simply the first person to accurately describe gravity and how it works both on Earth and in space.
Probably the first person who ever existed.

Anybody who lives on Earth experiences gravity.
The first person to formulate a comprehensive theory of gravity was Sir Isaac Newton in the late 17th century. He famously conceptualized gravity after observing an apple fall from a tree, leading him to consider the forces acting on objects both on Earth and in space. His work culminated in the publication of "Principia Mathematica" in 1687, where he described the law of universal gravitation. However, the concept of gravity existed prior to Newton, with philosophers like Aristotle discussing the nature of falling objects.
